Experimental measurements have been conducted to establish a correlation for the settling velocities of cylindrical particles whose length to diameter ratios varied from 10 to 1/10 and Reynolds numbers between 200 and 60,000. It was found that separate correlations exist for cylinders of L/D > 1.0 and for L/D < 1.0. These relationships are expressed analytically and were found to be independent of the Reynolds number. In addition, a qualitative description of the motion generated by the particle during settling has been discussed for cylinder of L/D less than, equal to, and greater than one.
